3 Overview
The Kramer VS-311HDMI is a high performance 3x1 HDCP (high definition
digital content protection) compatible
1
automatic switcher for HDMI signals,
digital audio (S/PDIF) signals, and stereo audio signals.
The VS-311HDMI switches any one of three HDMI HDCP compliant
1
sources to a single display device, on HDMI connectors with the
corresponding:
 Digital audio (S/PDIF) input signals switched to an S/PDIF output, on
RCA connectors and/or
 Unbalanced stereo audio input signals on 3.5 mini-jack connectors
switched to an unbalanced stereo audio output on a 3.5 mini-jack
connector, as well as to a balanced stereo audio output on a 5-pin terminal
block connector
The VS-311HDMI can operate either in the manual mode or in the auto mode.
In the manual mode, the VS-311HDMI acts as a regular switcher, switching
the input video and audio signals to the output via the three front panel
INPUT SELECT buttons.
In the auto mode, you can switch any input to the output via the three front
panel INPUT SELECT buttons, but once the selected video signal is lost, the
machine automatically switches to the highest priority input, according to the
input priority setup
2
. The VS-311HDMI will switch back to the primary input
when an HDMI signal is detected on that input.
The VS-311HDMI is housed in a desktop-sized enclosure and is 12 VDC fed.
Control the VS-311HDMI using the front panel buttons, or remotely via:
 RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
 The Kramer infra-red remote control transmitter
 The ETHERNET
 Remote control contact closure
1 HDCP is a standard, developed by Intel, to protect copyright holders (movie studios, and so on) from having their programs
copied and shared. The HDCP standard provides for the secure, encrypted transmission of digital signals over HDMI or DVI
connections between two HDCP-enabled devices. The source device (such as a DVD player or HDTV tuner) encrypts the
digital signal using the HDCP standard, and then sends that signal over the HDMI or DVI connection to the receiving device
(for example, an HDTV). The receiving device decodes the signal using HDCP and uses the signal as it is allowed

3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
1
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality. Note that
Kramer Electronics Limited is an HDMI Adopter
2
and an HDCP Licensee
3
.
In particular, HDMI:
 Provides a simple
4
interface between any audio/video source, such as a
set-top box, DVD player, or A/V receiver and video monitor, such as a
digital flat LCD / plasma television (DTV), over a single lengthy
5
cable
 Supports standard, enhanced, high-definition video, and multi-channel
digital audio
6
on a single cable
 Transmits all ATSC HDTV standards and supports 8-channel digital
audio, with bandwidth to spare to accommodate future enhancements and
requirements
 Benefits consumers by providing superior, uncompressed digital video
quality via a single cable
7
, and user-friendly connector
 Is backward-compatible with DVI (Digital Visual Interface)
 Supports two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
HDMI has the capacity to support existing high-definition video formats
(720p, 1080i, and 1080p/60), as well as standard definition formats such as
NTSC or PAL.
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
2 See http://www.hdmi.org/about/adopters_founders.asp
3 See http://www.digital-cp.com/list/
4 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
5 HDMI technology has been designed to use standard copper cable construction at up to 15m
6 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats
7 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

3.2 Recommendations for Best Performance
To achieve the best performance:
 Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
 Avoid interference from neighboring electrical appliances and position
your VS-311HDMI away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

Term Definition
802.3 The standard specification for ETHERNET that is maintained by the Institute of Electrical
and Electronics Engineers (IEEE).
Dynamic Host
Configuration
Protocol (DHCP)
Allows the network administrator to distribute IP addresses from a central point and
automatically send a new IP address when an Ethernet point is plugged into a different
network location
Gateway A network position serving as an entry to another network. On the Internet, a node or
stopping point can be either a gateway node or a host (end-point) node.
IP Address A 32-binary digit number that identifies each sender or receiver (within a network via a
particular server or workstation) of data (HTML pages or e-mails) that is sent in packets
across the Internet. Every device connected to an IP network must have a unique IP
address. This address is used to reference the specific unit.
Local Area Network
(LAN)
Computers sharing a common communications line or wireless link, which often share a
server within a defined geographic area.
Media Access
Control (MAC)
Address
A computer's unique hardware number (or address) in a LAN or other network. On an
Ethernet LAN, the (MAC) address is identical to the Ethernet address.
Transmission
Control
Protocol/Internet
Protocol (TCP/IP)
The basic communication language or protocol of the Internet that breaks the message
into appropriately sized packets for the network, and can be used as a communications
protocol in an intranet or an extranet.
